New proper motion determination of Luyten catalogue stars (LTT) south of declination -40 degrees and right ascension between 00 H and 04 H 30 M
Data are given for 104 LTT stars found on 11 areas, covering 25 squaresdegrees each, south of declination -40 degrees and right ascensionbetween 00 h and 04 h 30 m. Three stars present differences in propermotion greater than 0.10 arcsec, six present differences in positionangle greater than 20 degrees and one presents those differences in bothvalues.

Four-color UVBY and H-beta photometry of high-velocity and metal-poor stars. I - The catalogue of observations
A catalog of four-color uvby and H-beta photometry for 711 high-velocityand metal-poor stars is given. The selection of the stars and theobserving and reduction techniques used to obtain these data arediscussed. The photometry has been transformed closely onto the standarduvby-beta system. The errors of the data have been estimated using bothinternal and external comparisons. The data are uniform over the sky;that is, there are no significant north-south differences. For the largemajority of stars the mean errors of V, m1, c1, and beta are less than +or - 0.008 mag, and the error of b-y is less than + or - 0.005 mag.Values of V, b-y and beta and rough photometric classifications aregiven for 63 red and/or evolved stars that fall outside the range of thephotometric transformations.
